It's really good to see some well engineered PHP software coming out.<p>For my projects I've moved out to Python after having dealt with legacy trash like Wordpress, Google's api libraries, over-engineered frameworks like ZF and lets just say the less said about Propel the better.<p>Code like this, Symfony 2, Doctrine 2, Lithium etc... are a breath of fresh air. Their obviously written by a group of talented devs and after cutting ties with legacy PHP versions < 5.3 the future of "modern" PHP is looking bright!
